What is the radius of space travel? How "far" can a light speed space ship travel?

Question

So if you assume 7% of x must be less than 1 billion light-years in order to gain on the object despite the rate of the expansion of space we come up with this formula:

0.07x < 1 billion light years

and solving for x we get approximately:

x < 14.29 billion light years.

I wanted to know if people were coming up with the same numbers as me but clearly I posted this in the wrong forum. Your answers are similar to replying fifteen to a yes or no question, they weren't what I was looking for.

Answer 1

If you had an flashlight powerful enough, and you shined it straight ahead of you, the light would hit you in the back of the head.

Answer 2

Well, regardless of how large the universe may be or how fast it may be enlarging, any mass that is traveling at light speed would exist at every point of the space/time continuum simultaneously, thus would require an infinite amount of energy, hence, would be technically impossible according to the known laws of physics.

Answer 3

Would the universe be expanding at the speed of light as observed by you even though you are traveling that fast yourself.

Answer 4

we are only seeing the imaging of stars which sends out their light years or light years ago.  it might not be there when u reach it like a supernova, especially when the universe is expanding as you pointed out.

Answer 5

what

Answer 6

sorry but you&#039;ve got me a bit fuddled

Answer 7

Rather interesting.  If you assume an &quot;open&quot; universe that expands forever,  your ship could travel forever at nearly the speed of light without ever reaching the boundaries of space and time.

The Hubble constant is presently thought to be about 70

km/second/Megaparsec.   I&#039;m not sure what your 7% per billion years means, but using the above figure you can calculate the hypothetical answer to your question.
